摘要:以深共熔溶剂(Deep Eutectic Solvent,DES)-水混合物(LAEG40)作为提取溶剂,红景天苷提取率
为主要指标,酪醇提取率为辅助指标,在前期单因素实验的基础上,利用响应面法考察了液料比、提取温
度、提取时间 3 个主要因素对红景天中红景天苷和酪醇同步提取的影响。得到的最佳提取条件为:液料比
12.05∶1〔液体体积(mL)与固料质量(g)的比值,下同〕,提取温度 60 ℃,提取时间 35 min。在该条件下,
LAEG40 对红景天苷的提取率可达到 19.3552±0.6604 mg/g,酪醇提取率可达到 1.7211±0.0585 mg/g,远高于
传统溶剂水、乙醇对红景天苷和酪醇的提取率。为实现 LAEG40 提取红景天苷和酪醇的回收,进行了大孔
树脂吸附分离的研究。经过一系列优化,获得的最佳吸附分离条件为:选用 SP-825 树脂装柱,每 10 g 树
脂上样 30 mL LAEG40 提取液,洗脱剂选用体积分数为 80%乙醇,洗脱体积 40 mL,洗脱流速 1 mL/min,
在该条件下红景天苷和酪醇的回收率分别可达 60.47%和 85.07%。

Abstract: Taking deep eutectic solvent (DES)-water mixture (LAEG40) as extraction solvent, extraction
yield of salidroside as main index, extraction yield of tyrosol as auxiliary index, the effects of three main
parameters, solvent to solid ratio, extraction temperature and extraction time on the simultaneous extraction
of salidroside and tyrosol from Rhodiola rosea L were optimized by response surface methodology. The
optimal extraction conditions were obtained as follows: solvent to solid ratio of 12.05:1 (the ratio of liquid
volume to solid mass, mL/g, the same below), extraction temperature of 60 ℃ and extraction time of 35
min. Under these conditions, the extraction yield of salidroside reached 19.3552±0.6604 mg/g, and the
extraction yield of tyrosol reached 1.7211±0.0585 mg/g, which were much higher than those of traditional
solvents (water and ethanol). In order to recover the salidroside and tyrosol from the LAEG40 extraction
solution, the adsorption and separation method with macroporous resin was carried out. After systematical
optimization, the optimal conditions for adsorption and separation were obtained as follows: SP-825 as
